Ti-6Al-2Sn-4Zr-6Mo vs Ti-6Al-4V ELI (Grade 5 ELI): 87% composition overlap. Some similarities but notable differences in alloying elements.
Ti-6Al-2Sn-4Zr-6Mo vs Ti-6Al-4V ELI (Grade 5 ELI)
Side-by-side chemical composition and mechanical property comparison.
Overview
Ti-6Al-2Sn-4Zr-6Mo
Beta-rich alpha-beta titanium alloy — higher Mo (6%) than Ti-6242 for significantly higher strength (UTS 1100+ STA). Forged beta then STA (Solution Treat + Age) for peak properties. Used for high-compressor discs and blades in jet engines where strength at 300-450°C is critical. More Beta phase than 6242 = higher strength but lower creep resistance. AMS 4981.
Ti-6Al-4V ELI (Grade 5 ELI)
3.7165
Extra Low Interstitial version of Ti-6Al-4V — the standard titanium for surgical implants. Reduced O, N, C, Fe for improved ductility, fracture toughness, and biocompatibility. Used for hip and knee implants, bone screws, dental implants, spinal fusion devices, and cardiovascular stents. Also called Grade 23.
